Abstract (en)
A first base station (BS) connects to a communication device via a first cell, and transmits a Secondary Node (SN) Addition Request message to a second BS, to configure the second BS as a SN for the communication device in a dual connectivity (DC); the second BS transmits a SN Addition Request Acknowledge message comprising a first radio resource control (RRC) message to the first BS, wherein the first RRC message configures a second cell and comprises a first random access channel (RACH) configuration, the first RACH configuration configures at least one first RACH resource, and the first RRC message configures a first association configuration associating the at least one first RACH resource with a first synchronization signal block or a first channel state information reference signal transmitted via the second cell; the second BS communicating with the communication device via the second cell according to the first RRC message.
